Below is
what the RightLine Risk Control Calculator looks like when accessed
in your browser:

Rightline is serious about helping you protect your hard earned
capital. Our Risk Control Calculator helps you
manage risk by recommending a position size or maximum number
of shares to purchase.

Though you are able to calculate risk
at any percentage you deem acceptable, as a rule of thumb,
traders with six figure accounts should risk no more than
2 percent, while smaller accounts should risk no more than
4 percent.

Regardless of the exact percentage you choose,
never risk more than you can feel comfortable losing.
